In the current issue of Science, researchers at Michigan State University demonstrate how a new virus evolves, which sheds light on how easy it can be for diseases to gain dangerous mutations.
The scientists showed for the first time how the virus called "Lambda" evolved to find a new way to ... Read More
Norovirus, a pathogen that often causes food poisoning and gastroenteritis, was responsible for 18.2 percent of all infection outbreaks and 65 percent of ward closures in U.S. hospitals during a two-year period, according to a new study published in the February issue of the American Journal of ...

If you’re paying premium prices for pesticide- and antibiotic-free meat, you might expect that it’s also free of antibiotic-resistant bacteria. Not so, according to a new study. The prevalence ofone of the world’s most dangerous drug-resistant microbe strains is similar in retail pork products l... Read More
In response to recent actions of the U.S. National Science Advisory Board for Biosecurity (NSABB), which recommended that two scientific journals withhold crucial details in upcoming reports about experiments with a novel strain of the bird flu virus, H5N1, the American Society for Microbiology ...

Scientists have shed new light on the way superbugs such as MRSA are able to become resistant to treatment with antibiotics.
Researchers have mapped the complex molecular structure of an enzyme found in many bacteria. These molecules – known as restriction enzymes – control the speed at which... Read More
A spore from the bacterium Bacillus subtilis shows four outer layers that protect the cell from harsh environmental conditions.
Bacillus subtilis is a ubiquitous bacterium commonly recovered from water, soil, air, and decomposing plant residue. The bacterium produces an endospore that allows... Read More
Scientists have shown for the first time how a new virus evolves, clarifying how easy it is for diseases to quickly gain dangerous mutations.
Published in the journal Science, the research shows how the virus Lambda evolved to find a new way to attack host cells, an innovation that took four ... Read More
The use of probiotic bacteria, isolated from naturally-occurring bacterial communities, is gaining in popularity in the aquaculture industry as the preferred, environmentally-friendly management alternative to the use of antibiotics and other antimicrobials for disease prevention. Known to the p... Read More
Among medical mysteries baffling many infectious disease experts is exactly how the deadly pneumonic plague bacterium, Yersinia pestis, goes undetected in the first few day of lung infection, often until it's too late for medical treatment.
New research from the University of North Carolina a... Read More
Health officials in Las Vegas said Monday that the bacteria that causes Legionnaires' disease was found in water samples at the Luxor hotel-casino this month after a guest died of the form of pneumonia.
The Southern Nevada Health District said the Centers for Disease Control and Prevention na... Read More
The US National Science Advisory Board for Biosecurity (NSABB) recently recommended that journals Nature and Science remove certain methodological details from controversial studies on the avian influenza virus (H5N1) to minimize the risk of these findings being misused by would-be bioterrorists...

Pneumococcus (Streptococcus pneumoniae) causes potentially life-threatening diseases including pneumonia and meningitis. Pneumococcal infections are thought to kill approximately a million young children worldwide each year, although the success of vaccination programmes has led to a dramatic fa... Read More
Natural selection is a kind of search engine. Given enough time, and suitably vast populations, it should find the best solutions repeatedly. So why are bacteria still bacteria? And why did all complex life on our planet share an ancestor that only arose once in four billion years? In this lectu... Read More
Under the microscope, an E. coli cell lights up like a fireball. Each bright dot marks a surface protein that tells the bacteria to move toward or away from nearby food and toxins. Using a new imaging technique, researchers can map the proteins one at a time and combine them into a single image.... Read More
A few weeks ago a clinic in Mumbai claimed to have identified a dozen patients with a strain of tuberculosis (TB) resistant to all known treatments. TB is a highly contagious lung infection that kills about 1.5 million people each year worldwide, according to the World Health Organization (WHO),... Read More
A team of biologists at the University of York has made an important advance in our understanding of the way cholera attacks the body. The discovery could help scientists target treatments for the globally significant intestinal disease which kills more than 100,000 people every year.
The dis... Read More
Standing as the most densely populated city in the world, New Delhi has plenty of public health issues to deal with on a constant basis. But now health officials have some very urgent matters to deal with: new strains of super-bacteria, the most destructive of which contain the gene dubbed NDM-1... Read More
Some bacteria can evade efforts to vaccinate against them by wearing a new disguise, researchers say.
A study, published in Nature Genetics, tracked how pneumococcus bacteria responded to the introduction of a vaccine in the US in 2000.
Doctors said the evasion would make some vaccines les... Read More
